摘要：
A least-squares mixed finite element (LSM) method is formulated for a class of Sobolev equations in two dimensional domains. Optimal L-2 -error estimates are derived under the standard regularity assumption on the finite element partition (the LBB-condition is not required). Optimal L-2 estimates are derived under the conventional Raviart-Thomas spaces.
